TO ALL WHOM IT MAL7 OONCERN:

Be it known that we, WILLIAM A. MORSE and JOHN G. POWELL, of Philadelphia., in the county of Philadelphia, in the State of Pennsylvania, have invented anew and improved Eraser and PensHandle Combined; and we do hereby declare that the following is a full and exact description of the constructionand operation of the saine, reference being'had to the accompanying drawing, and to the letters ot' reference marked thereon.

The nature of our invention consists in an eraser of peculiar construction, whereby We are able to vproduce a superior article at a much less cost than heretofore, or at about the cost oi' steel pens, in combination with either the top end or the tip of a. pen-handle.

'lo enahlcrothers skilled in the art to make and use our invention, we will proceed to describe its construction and op`eration. f

We make our eraser of thin sheet steel, such as is commonly used in the manufacture of steel pens, though it may be a little heavier, if" desirable. 7e cut it out with a die and punch of' desirable form, usually conical, the blade being widest near its point and tapering to the end of its shank. This conical-shaped blade we press in a concave die of the saine conical form, the surface of which represents nearly haii` a circle. ln pressing it we use a convex-faced punch made to {it the die loosely. This operation produces in form our improved eraser, its outer surface, m, being the saine as the inner surface of the die, and its inner or concave surface, s, takes the form of the face of the punch. Its sides, from its point to the end of its shank, represent the arc of a. circle, reckoning at right angles with its length, thus presenting a concave, s, and a convex surface, m. This forni stiffcns thc blade and at the same time produces a s'uperior form for au eraser and burnisher, which requires niuch less labor than is common on such goods to finishit. We grind theface edges c c on the concave side parallel, which produces a cutting edge all-around; then polish the back or convex surface, m, and it is done. We then put the smallest end into the top of the pen-handle A, previously prepared to receive it, or place it into the tip the same as a steel pen. It may be used with equal facility and ease at either end. Therefore, We do not coniineourselves toveither particular ivay.

The operation of erasing is the same as with other edged instruments, after which the convex surface m is rubbed over the erased puper to burnish it and make it hard.

Having thus fullydescribed the construction and operation of our improved eraseraud pen-handle eon1- bined, what We claim as our invention, and desire to secure by Letters Patent, is

l. `We elainl the eraser'and burnisher B, with its parallel face edges c c, for sharpening, its concave surface 8 and convex surface Im extending its whole length, in combination, substantially as described and shown, and for the purpose set forth.

2. Constructing the eraser B of' such form that it can hc inserted at either the top or the tip of the pexbhandle A, substantially as specified and forthe purpose-set forth.
